Program-specific files
======================

  Many programs will need to find some configuration files.  Kpathsea
contains some support to make it easy to place them in their own
directories.  The Standard TeX directory structure (*note Introduction:
(tds)Top.), specifies that such files should go into a subdirectory
named after the program, like `texmf/ttf2pk'.

  Two special formats, `kpse_program_text_format' and
`kpse_program_binary_format' exist, which use `.:$TEXMF/PROGRAM//' as
their compiled-in search path.  To override this default, you can use
the variable `PROGRAMINPUTS' in the environment and/or `texmf.cnf'.
That is to say, the name of the variable is constructed by converting
the name of the program to upper case, and appending `INPUTS'.

  The only difference between these two formats is whether
`kpse_open_file' will open the files it finds in text or binary mode.
